The new retail price is $5000. My senior friend used it for 1 week (therefore it is virtually brand NEW) and unfortunately no longer requires it.
This brand is Japanese made and is probably the best in the world. The LeveLuk SD 501 is Enagic's Flagship Model.
The industry-leading continuous ionized electrolysis water generator system, the SD501 is the finest machine in its class. With the strongest electrolysis chamber available, fully-equipped with a built-in electrolysis chamber, and featuring a large LCD panel and clear voice prompts, the SD501 is the leader of the pack. 7-Platinum-plated Titanium plates comprise the electrolysis chamber.
